Microfluidic device.

<p>(3a) Schematic of the entire plate. The microfluidic module itself was 25 × 50 mm, which was extended to 25 × 75 mm by the addition of a plastic adapter plate. (3b) Channel geometry within the microfluidic device. The image was taken using DIRI (Darkfield Internal Reflection Illumination). Port A is the inflow port, and port D is the outflow port. Ports B and C are closed during the experiment.
